Apparatus and method for manufacturing transparent synthetic resin vessel with integrated handle

Abstract

An apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle are provided. The transparent synthetic resin vessel manufacturing apparatus includes: an upper mold being vertically movable and having a core and a core block; a fixing plate having rib members; a rotating plate being vertically movable together with the upper mold and having a rotating device for simultaneously molding the handle on one side of a preform and manufacturing a transparent synthetic resin vessel; a fixing member for joining the fixing plate with the rotating plate; a lower mold supplied with molten resin at one side thereof so as to injection-mold the handle; an injection mold for forming the preform into a transparent synthetic resin vessel; and a vessel separator for separating the transparent synthetic resin vessel from the vessel manufacturing apparatus.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to an apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle. More particularly, the present invention relates to an apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle, which can injection-mold a handle in a vessel forming preform and automatically discharge the molded vessel from a mold, thereby manufacturing the transparent synthetic resin vessels on a mass production basis and reducing manufacturing costs because the transparent synthetic resin vessel with the integrated handle is manufactured by just a single process without additional process to attach the handle and being recycled without needing to separate raw materials because the transparent synthetic resin vessel is made from just one material.[0002]In general, beverages of various kinds, water, and cooking oil, soy sources, vinegar, and so on used for cooking...

Benefits of technology

[0014]Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide an apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle, which can injection-mold a handle in a vessel forming preform and automatically discharge the molded vessel from a mold, thereby manufacturing the transparent synthetic resin vessels on a mass production basis and reducing manufacturing costs because the transparent synthetic resin vessel with the integrated handle is manufactured by just a single process without additional process to attach the handle.

[0015]It is another object of the present invention to provide an apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle, which the transparent synthetic resin vessel is made from just one material, thereby being recycled conveniently without needing to separate raw materials.

[0016]It is a further object of the present invention to provide an apparatus and a method for manufacturing a transparent synthetic resin vessel with an integrated handle, which the handle is injection-molded integrally to a body of the transparent synthetic resin vessel, thereby enhancing bearing power and solidity when a user uses the handle of the transparent synthetic resin vessel, enhancing durability of the transparent synthetic resin vessel and securing stability in handling and use.

Problems solved by technology

However, such a plastic bottle has a problem in that the handle easily falls out due to an unsound fixed portion when external impact or load is applied to the plastic bottle because the handle is not molded integrally during the injection-molding process but is fixed to the plastic bottle after being molded through a separate process.

Furthermore, the conventional plastic bottle has further problems in that material consumption is increased, a difficult process for fixing the handle to the neck portion of the plastic bottle is needed, and it takes lots of working time because the fixed portion, namely, the neck portion to which the handle is fixed must be thicker than other portions in order to endure a load due to fixation.

Additionally, the conventional plastic bottle has another problem in that solidity of the fixed portion is deteriorated due to a material difference because the material of the plastic bottle and the material of the handle are different from each other.

However, such a handle molding method has several problems as follows.

The handle molding method has a problem in that it is difficult to correctly form the shape of the handle because a peripheral portion of the handle part is also pushed in when the slide core is pushed in and drawn at high pressure so as to form the handles at both sides of the plastic bottle.

Moreover, the handle molding method has another problem in that the handle may be damaged by weight during the use in the case of a large-capacity plastic bottle because the outer circumference is cooled after being formed thinner than a vertex portion corresponding to the slide while being pushed and pulled when the slide core is pushed inwardly in a state where heat still remains in the plastic container body.

However, the P.E.T container according to the prior art has several problems in that manufacturing expenses and costs are increased due to a complicated structure of the mold for forming the P.E.T container, and in that it is difficult to manufacture the P.E.T container on a mass production basis and manufacturing efficiency of the P.E.T container is considerably decreased a cycle period of time required for the injection molding is too long.
